How this service works
The premier global index of 1,069 monetized MCP nodes across 205 specialized subdomains. Gasless USDC runtime settlements via x402 V2 Spec on Base L2. Save 95% token context.
Output
Returns a verification result indicating whether the provided L402 payment credential or proof is valid across the specified blockchain networks, including validity status and any relevant chain confirmation details.
Example use cases
Gating API access with L402 tokens
“I need to check whether this L402 bearer token from my user is a legitimate cross-chain payment proof before I grant them access to premium content — here's the token string, can you verify it?”
Multi-chain payment receipt validation
“A user claims they paid on a different chain than our main one — can you validate their L402 payment proof to confirm the transaction is real and the credential is authentic?”
Cross-chain subscription verification
“Before renewing this subscriber's access, verify their L402 credential to make sure their cross-chain payment went through and the proof is cryptographically valid.”
Technical details
Endpoint
POSThttps://api.m2mcent.com/cross-chain-l402-verifier-mcp/api/process?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to verify L402 payment credentials that span multiple blockchain networks, particularly when a single-chain validator is insufficient. Ideal for multi-chain payment gating, cross-chain subscription systems, or any workflow where L402 tokens must be authenticated across heterogeneous chains.
Side effects
- Invalid or malformed L402 token returns a verification failure
- Unsupported blockchain network results in an error response
- Expired credential may return invalid status
- Missing or empty data field returns a bad request error
- Network timeout if cross-chain lookup takes too long
